Hello,
It looks like Sweet Viburnum and it's not definitely tea olive. Tea olive leaves are matte and also called sweet olive is best fragrant shrub I have ever seen. It produces fragrant flowers twice a year however flowers are so tiny and not very noticeable but apricot fragrance will blow your mind. I have 7 of them all over in my yard. I also have the Viburnum Chindo and gets very large but is not very fragrant only plus side is very shiny leaves.
Thanks ,
Ridvan
